<u>Answer:</u> The partial pressure of helium gas is 0.80 atm
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the partial pressure of helium gas, we use the law given by Dalton, which is:

We are given:
Total pressure of the cylinder,
= 1.00 atm
Vapor pressure of oxygen gas,
= 0.20 atm
Putting values in above equation, we get:

Hence, the partial pressure of helium gas is 0.80 atm
Gold alloys consist of most commonly Nickel!
Most commonly used in things like jewelry so it doesn't have such a heavy weight.
Yea it's c it's a living component
Answer:
<h3>2CH3COOH(l)⇒⇒⇒⇒(CH3COOH2)+ + (CH3COO)-</h3>
Explanation:
Remember that, ionization is a process by which an atom or a molecule receives a negative or positive charge by gaining or losing electrons during a chemical reaction. However the auto-ionization reaction for acetic acid the two solvent molecules (CH3COOH2)+ + (CH3COO-) collide and a proton is transferred between them.
